It is not possible to use line current directly for measurement and relaying purpose due to its high value and insulation problem. CURRENT TRANSFORMER which is widely known as 'CT' is a piece of electrical equipment which converts line current ( primary current ) in to small standard current values which are suitable for the devices to which it is connected e.g. measuring instruments, meters, protection relays.
 
 
Basic Functions for Current Transformers
 
To reduce line current to a value which is suitable for standard measuring instruments, relays etc.
To isolate the measuring instruments, meters, relays etc. from line voltage of an installation.
To protect measuring instruments against short circuit currents.
To sense abnormalities in current and give current signals to protective relays to isolate the defective system
 
CURRENT TRANSFORMERS ARE BROADLY CLASSIFIED AS
 
Ring Type Current Transformers
   
Bar Primery Current Transformers
   
Wound Type Current Transformers
 
CURRENT TRANSFORMERS are also classified in accordance with their nature of application, i.e.
 
Measuring Current Transformers
 
Protective Current Transformers
 
FOLLOWING ARE FEW GENERAL TYPES
 
Interposing CT
Summation CT
BUSHING TYPE OR BUSDUCT CT
CORE BALANCE CT
